Will mark brainliest answer if  

x=4 and y=2

Step-by-step explanation:

Name the triangles as ABC and DEF,

Now, since both the triangles are congruent by HL rule, therefore

                     (1)

and                (2)

Substituting the value of    in equation (1), we get

Therefore, Putting y=2 in equation (2),

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
